M7410E

SMALL MODULATING LINEAR

VALVE ACTUATOR

PRODUCT DATA

APPLICATION

The Honeywell M7410E actuator is specifically designed to provide modulating control together with the V5822/23, V5832/33, and V5825B series of small linear valves.

The M7410E is used in fan-coil-units, induction units, small reheaters and recoolers, and for zone control applications. It is employed in electronic temperature control systems with hot and/or cold water as the controlled medium. This actuator is fully compatible with all controllers providing 0...10 V or

2...10 V output signals. The 7410E actuator is designed for applications where space

is limited and minimum power consumption is required. A microprocessor-based, high-performance positioner

guarantees accurate control. Reliable longtime operation is ensured due to the fact that no

mechanical feedback potentiometer and no mechanical endswitches are needed. Due to an automatic synchronization function, the close-off point is self-adjusting.

Based on a running time of 150 s, valve positioning and flow adjustment is very exact. Manual positioning is provided for all actuators. The actuator is both attractive and robust in design. A special version with auxiliary switch is available.

FEATURES

• Microprocessor-based positioner ensures precise

stem positioning

• Small size allows installation where space is limited

• Low power consumption

• Suitable for 0...10 V and 2...10 V controller output

signal (adjustable on site)

• Easy-to-operate direct/reverse acting switch

• Simple input signal override (e.g. for frost protection

function)

• Reliable longtime operation because mechanical

feedback potentiometers and mechanical end switches are not required

• Magnetic coupling for stem force limitation and self-

adjustment of the close-off point

• Supplied with pre-wired connection cable

• Simple, standardized valve/actuator coupling. No

tools required for mounting

• Visual valve position indicator furnished with

actuator

• Manual operation provided by the valve adjustment

cap, extra knob, or with a hexagon key

OPERATION

The movement of the electric actuator is produced by a screw spindle which is driven in both directions by a synchronous motor through a set of gears. A magnetic clutch limits the torque of the gear assembly and the driving force of the actuator. The actuator is fixed to the valve body by means of a coupling ring requiring no tools for mounting. The actuator is maintenance-free and supplied completely with a ready-towire connecting cable.

A microprocessor-based high performance positioner guarantees accurate control. The close-off position is selfadjusting by means of an automatic synchronization function. Synchronization is performed when the applied control signal is 0 V or 10 V. The actuator then drives every minute for 5 seconds into the end position in order to ensure close-off even after manual operation.
